Foil insulation roll, also known as multifoil insulation, is a type of insulation made up of layers of sheets, foils, and insulating materials. It is designed to provide thermal efficiency by reflecting heat back into the building and creating a barrier against solar heat gain. Foil insulation is one of the thinnest insulation products on the market, making it ideal for use in lofts and tight spaces. It offers high performance in a slim profile compared to traditional insulation materials, reducing heat loss and improving thermal comfort. Foil insulation is energy-efficient, easy to handle, has a long lifespan, saves space, and is simple to install.
